Nitrous oxide is a colorless gas consisting of two atoms of nitrogen and one of oxygen. It is commonly known as "laughing gas" because of the sense euphoria it produces and it also has a potential for abuse.

N2O:
Some people like it because it relaxes them and they feel as though they have had a couple of glasses of wine. Other people hate it as it makes them uncomfortable and some say claustrophobic. Good news is room air gets it out of your system very fast within a minute or two so try it first before you commit to a procedure. Have your dentist or md let you try it first.

Yes:
People have died while using nitrous oxide recreationally. It is due to the lack of oxygen, not the danger inherent in the drug itself. Professionally administered it is extremely safe. Reducing anxiety actually can make dental procedures safer. Prolonged, excessive exposure to nitrous oxide can cause neurological problems. And it's use during pregnancy and by pregnant team members is unwise.

Not particularly:
It doesn't force you to lie, either. Its feeling is one of disassociation, like you're floating. But you can still hear and understand what you are being asked and it does not force you to answer in any specific way.

Nitrous Oxide::
When some patients get too high a concentration, especially on a full stomach, they may feel nauseous and then regurgitate. See: http://en. Wikipedia. Org/wiki/nitrous_oxide dentists use nitrous oxide and oxygen to relax patients during dental procedures.

Nitrous oxide:
Nitrous oxide is a colorless gas consisting of two atoms of nitrogen and one of oxygen. It is commonly known as "laughing gas" because of the sense euphoria it produces and it also has a potential for abuse.

Absolutely!:
The majority of my patients love it, and once they try it request it for dental procedures even if they don't really need it. There are a few people with claustrophobia who panic or will not try it. That's unfortunate as it is truly a great aid in relaxing patients and making the entire dental visit so much easier.

Sleepiness, nausea:
Nitrous oxide is a gas that can be used as a component of general anesthesia. It is a weak anesthetic in its own right, and is sometimes used in dental offices to supplement pain relief. Its main effect is drowsiness or sleep, and the most common side effect is nausea. Nitrous oxide is used much less in anesthesia today since we have other, more potent anesthetic gases in wide use.

14

Yes.:
I am assuming this is for a dental appointment or some similar medical reason and not for recreation. It is only safe under the supervision of a trained medico. Partying with nitrous oxide can result in brain damage or even death because no one is making sure you get enough oxygen!

15

None:
Nitrous oxide is a vapor with rapid onset and offset, poor anesthesia (amnesia) maintenance, and excellent analgesia in high concentrations. As such, it is unique in its properties. There are intravenous equivalents, but none that can be simply breathed. It's major side-effect is nausea and vomiting, so it's popularity as an anesthesia adjunct in diminishing

16

Lack of Oxygen:
The damage is in the "lack of oxygen" part. The lack of n20 isn't in question here. If too much n20 were to become part of that mixture, reducing the o2 concentration to less than 21%, that could lead to dangerous hypoxemia (lack of o2). This will compromise o2 delivery to your brain and other vital organs, putting them at risk for metabolic failure and even cell death. To be avoided!

18

Plenty:
Nitrous oxide is not a complete anesthetic. Any other inhaled agent can be substituted, and there are many intravenous agents that can also serve the purpose. In general, nitrous oxide is considered to be relatively innocuous.

19

A nice aid:
It is a gas used to lessen apprehension during medical and dental procedures. In most cases, you are awake and can communicate, but you are not as focused on what is being done at the time. It is a nice experience for most patients.

20

Not being aware:
Of your environment does not mean that you will die. What is important is that the medical provider taking care of your anesthesia is well trained. If you were a high risk patient I would think that you would have already been told that by now.
